2,5-Dimethoxytetrahydrofuran [ 696-59-3 ]
Purity: 98%. A colourless liquid. The boiling point 145-147 ℃, 52-54 ℃ (2.93 kPa), relative density 1.023 (20/4 ℃), the refractive indexes, 1.4182-35 ℃ 1.4184 and flash point. With water, ethanol, ethyl ether immiscible. Heated easy to resolve. For an anticholinergic drug atropine sulfate intermediates. Is also used for photographic films. Due to establish THF with low boiling point, good fluidity and for many chemicals soluble strong, resin to the surface and inner of avian good characteristic, commonly known as the "universal solvent". Widely used in plastic, rubber, coating, adhesive, printing ink, textile, pharmaceutical and other industries.
